EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 767,617, dated August16, 1904.

Application filed March 4, 1904:. Serial N0. 196,586. (N0 model.)

To all 1072 0712, it nuty concern:

Be it known that 1, JOHN W. J. lVnLLs, a citizen of the United States,residing at M eso, in the county of Jefferson and State of Illinois,have invented certain new and useful Improvements in Eyeglasses, ofwhich the following is a specification.

The purpose of this invention is to provide a structure of eyeglasses orspectacles combining in a single article lenses of different focuses,whereby the same may be used for different purposes-for instance, forreading or long-distance uses.

The invention particularly relates to spectacles providing a pair ofsupplemental lenses movably mounted upon the frame of the spectacles, soas to be readily brought into use when desired.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings.

l/Vhile the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which Figure 1is a perspective view showing'the embodiment of the invention, thesupplemental lenses being shown in the positions assumed thereby whenout of use. Fig. 2 is a top plan view showing the relative position ofthe lenses when in use. Fig. 3 is a detail view, enlarged, showing moreclearly the manner of mounting the supplemental eyeglass-lenses upon theframe of the spectacles. Fig. 4c is a vertical sectional view, partiallybroken away, showing the engaging action of the projections 12 of thestuds 5.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The spectacles shown in the drawings are of common type and comprise theframe, consisting of the bows 1, the connecting nose-piece 2, and thelenses 3, secured in the bows of said frame. The temples 4c are pivotedto the cus from the lenses 3, mounted in the bows 1.

-It will be obvious that any character of lens 7 may be disposed withinthe supplemental bows 6 within the contemplation of my invention, andthis feature would of course depend greatly upon the affection of theeyes of the wearer of the spectacles.

As before premised, the studs 5 are specially formed, being composed ofspaced members 5 and 5". studs 5 are enlarged between theends thereof,as shown at 8, and the enlarged portions 8 are provided with openings toreceiveascrew or similar fastening 9, by which the supplemental bow 6 ispivotally mounted upon the stud. The temples 1 are pivotally securedbetween -the outer end portions of the studs 5 by means of ascrew-fastening or similar device also.

In order that the supplemental lenses may be disposed close againstthemain-lenses 3 when the said supplemental lenses are in use, the studs5 are deflected or curved from the plane of the frame of the spectacles.The form of the studs 5 thus admits of the disposal of the lenses 7 inthe positions above mentioned.

When the lenses '7 are not in use, they are bya pivotal movement turnedbackward from the lenses 3 approximately in contact with the temples 4,as shown most clearly in Fig. 1 of the drawings. The use and operationof the spectacles or eyeglasses are obvious and need not be described indetail.

Because of the manner of mounting the supplemental bows 6 it is verydesirable that some means be provided for positively holding thesupplemental lenses adjacent the main lenses 3 'or in the reverseposition assumed by the supplemental lenses when not in use. For theabove purpose the pivot member 10 of each supplemental how 6, which isreceived between the spaced members 5 and 5 of the cooperating stud, hasformed upon the upper The members 5 and 5 of the side thereof a recessor depression 11. The uppermost spaced member 5" of the stud 5 isprovided with adjacent projections 12, which are adapted to spring intoengagement with the recess or depression 11 of the pivot member 10 topositively lock the supplemental lens in either of the positions aboveset forth. The projections 12 have a spring action.

Having thus described the invention, what is claimed as new is 1. Ineyeglasses or spectacles, the combination of a frame composed of bows,studs projected from the bows and comprising spaced members,supplemental bows provided With pivot members projected therefrom andpivoted between the spaced members of the studs aforesaid, said pivotmembers of the supplemental bows being provided with a depression orrecess, and independent spring projections integrally formed with one ofthe spaced members of each of the studs and JOHN W. J. ELLS.
